参阅图1～图3，本申请一实施例提供一种风道组件100，包括蜗舌10及蜗壳20。Referring to FIGS. 1 to 3 , an embodiment of the present application provides an air duct assembly 100 including a volute tongue 10 and a volute 20 .

蜗舌10内部具有容纳腔11，蜗舌10开设有与容纳腔11连通的敞口12，蜗壳20安装于敞口12处。具体地，蜗壳20安装于敞口12处，以与蜗舌10界定出用于气流流通的第一进风口和第一出风口。The volute tongue 10 has an accommodating cavity 11 inside, the volute tongue 10 is provided with an opening 12 communicating with the accommodating cavity 11, and the volute 20 is installed at the opening 12. Specifically, the volute 20 is installed at the opening 12 to define a first air inlet and a first air outlet with the volute tongue 10 for airflow.

其中，蜗舌10包括两个侧板13、第一板110和第二板120。两个侧板沿第一方向相对，且分别与蜗壳20相抵，以使蜗壳20沿第一方向支撑蜗舌10。第一板110和第二板120沿第二方向相对。第一板110和第二板120沿第一方向的端部分别与两个侧板13相连，从而形成所述容纳腔11。蜗壳20与蜗舌10的的第一板110连接。蜗舌10的第一板110上设有第一定位部14，蜗壳20设有与第一定位部14相适配的第二定位部21，以使蜗舌10沿第二方向定位蜗壳20，第二方向与第一方向垂直。The volute tongue 10 includes two side plates 13 , a first plate 110 and a second plate 120 . The two side plates are opposite to each other along the first direction, and are respectively abutted against the volute case 20 , so that the volute case 20 supports the volute tongue 10 along the first direction. The first plate 110 and the second plate 120 are opposite in the second direction. Ends of the first plate 110 and the second plate 120 along the first direction are respectively connected with the two side plates 13 to form the accommodating cavity 11 . The volute 20 is connected to the first plate 110 of the volute tongue 10 . The first plate 110 of the volute tongue 10 is provided with a first positioning portion 14, and the volute 20 is provided with a second positioning portion 21 adapted to the first positioning portion 14, so that the volute tongue 10 can be positioned along the second direction of the volute case 20. The second direction is perpendicular to the first direction.

当蜗舌10和蜗壳20注塑成型后，由于使用的材料易变形，导致蜗舌10和蜗壳20易变形，特别是在敞口12处，容易导致蜗舌10塌陷。在本公开中，通过沿第一方向相对的两个侧板13分别与蜗壳20相抵，可使蜗壳20在敞口12处支撑蜗舌10，从而抑制蜗舌10在敞口12处沿第一方向的变形；通过在蜗舌10的第一板110上设置第一定位部14，蜗壳20上设置有与第一定位部14相适配的第二定位部21，以使蜗壳20能够对敞口12处沿第一方向进行可靠支撑的同时，也抑制了蜗壳20在敞口12处沿第二方向的变形，并且可反作用抑制蜗舌10在敞口12处沿第二方向的变形。After the volute tongue 10 and the volute case 20 are injection-molded, the volute tongue 10 and the volute case 20 are easily deformed because the materials used are easily deformed, especially at the opening 12 , which easily causes the volute tongue 10 to collapse. In the present disclosure, the two side plates 13 opposite along the first direction are respectively abutted against the volute 20, so that the volute 20 can support the volute 10 at the opening 12, thereby restraining the volute 10 from sliding along the opening 12.
